Write a program convert a cent to dollars and cents in python
The Correct Answer and Explanation is :
Here’s a simple Python program that converts cents to dollars and cents:
def convert_cents_to_dollars(cents):
# Validate input
if not isinstance(cents, int) or cents < 0:
return "Please enter a non-negative integer for cents."
# Calculate dollars and remaining cents
dollars = cents // 100 # Integer division to get the dollar amount
remaining_cents = cents % 100 # Modulus to get the remaining cents
return f"${dollars}.{remaining_cents:02d}"
# Example usage
cents_input = 150
result = convert_cents_to_dollars(cents_input)
print(f"{cents_input} cents is equal to {result}.")
Explanation
- Function Definition: The program defines a function named
convert_cents_to_dollarsthat takes one argument,cents. This argument is expected to be a non-negative integer representing the amount in cents. - Input Validation: The first step within the function is to validate the input. It checks if the input is an integer and whether it is non-negative. If the validation fails, it returns a message prompting the user to enter a valid amount.
- Calculating Dollars: The function calculates the dollar amount by performing integer division of
centsby 100. This operation gives the total number of whole dollars. - Calculating Remaining Cents: The remaining cents are calculated using the modulus operator (
%). This gives the remainder of the cents after dividing by 100, which represents the cents left over after converting to dollars. - Formatting the Output: The function returns a formatted string that displays the dollar amount and the cents. The
remaining_centsis formatted to always show two digits, ensuring consistency (e.g., 05 instead of just 5). - Example Usage: An example usage of the function is provided where
150cents is converted. The output displays both the input in cents and the converted result in the dollar format.
This program can be further enhanced by incorporating user input functionality and error handling for a more robust application, but the core logic remains effective for basic conversions.
